Main uses:

This valve is a ventilation device installed on a fixed top tank, which reduces oil evaporation loss, controls tank pressure, and prevents external flames from entering.

The valve is installed in the fixed roof tank ventilation, reduce the evaporation loss, control the tank pressure and prevent external flame spread.

Main features:

This valve has the characteristics of high ventilation, low leakage, corrosion resistance, and is equipped with an electrostatic grounding wire to maintain an equipotential between the valve and the tank. This valve has anti freezing performance and is suitable for cold regions.

The valve has a large amount of ventilation, a small amount of leakage, corrosion resistance and other characteristics, and static grounding wire, so that the valve and the tank to keep other potential. The valve has a freezing resistance, suitable for cold area.
